I have a .jrxml file and I would like to pass some params from the code to it. I have an Order class that has fields like double price, int quantity and Product product. The situation is simple, when i need to pass price or quantity, I just do something like this:

The prefix is... can be used for methods that return a primitive boolean. However, your field activeRecord is of type Boolean, which is an object (the wrapper type of boolean), and for objects you always need to use get....

I am developing a report on Jaspersoft Studio 6.4.0 and I use JavaBeans as data sources.

I need to change the background color of a textfield dynamically. In fact I have a color variable in my bean which is calculated like this :

Color resultColor = new Color(255, (int) (ratio * 5.1), 0);

Where ratio is a double calculated with the variable in the textfield.

I have two possibilities, the first one is to give a Color to my jasper report and the second one is to calculate the green and red ratio and make the color in
a conditionnal style.
I don't know where I can put this kind of dynamic color, can you help me?

I want to map my DataBean(TestModelA) to existing XML, but JasperReports gives me an exception. The problem is that I have custom field (TestModelB) and I have public getters and setters in that class, but jasper does not recognize them. How can i solve this problem?

Answer:

Your are passing TestModelA class as datasource you need either to create the method in this class or reference the method correctly from jasper report.

I tried with subreports. but there I couldn't find a way to pass the params.
Also tried with collection datasource also. There the problem I found was need to mention the factory method. My requirement is to create this report dynamically.

Company info show up fine in the Master report however, no orders in details are printed from the sub report. When I print the subreport, there is data (ie, detail of orders) showing up as expected. I just want to pass the subreport in the detail section of the master, and everything will be perfect.

Answer:

If you want to use "companyOrders" as a field in your reports you have to put it in your "ACompany" POJO, more or less like that :
